As much as Jim enjoyed working out at the gym, part of the reason for going was always for the sauna afterwards. Situated at the end of the shower area in the men's changing rooms, Jim liked to sit facing the door so he could enjoy watching all the numerous naked bodies soaping themselves up.
With only a dim light inside, and darkened glass in the door, he could happily sit naked himself and stare at the bodies without being noticed, and while some didn't excite him, there was generally at least one for him to create a fantasy with while he sweated away in the sauna.
Today was a quiet day at the gym, and in the ten minutes that Jim had so far been in the sauna, there had only been one man that had got Jim fantasizing. Unfortunately, that man had finished showering and gone to get dressed, so seeing no one else to watch, Jim lied back on the bench and closed his eyes to continue his previous fantasy.
A noise stirred Jim back to reality, and it took him a brief moment to remember where he was and realize that the noise was the sauna door opening. "Morning" said the man entering the sauna and sitting down on the other side to Jim. "Morning" replied Jim as he sat up and tried to subtly check out the person interrupting his sauna.
